Answer:
17 meters
Step-by-step explanation:
The perimeter is the addition of all sides. Since the perimeter is 68 meters and a square has 4 sides, we can divide 68 by 4 and we get 17.
Answer:
The distance between these two is 3 3/5
Step-by-step explanation:
In order to find the distance between two points, we subtract one from the other. Then if the result is negative, we take the absolute value.
2 3/5 - -1
2 3/5 + 1
3 3/5
B) (-4, -4)
When moving to the right you are moving to a more POSITIVE region on the x-axis; meaning, the y-value (vertical axis) does not get affected unless you’re moving up or down.
Remember: (-6, -4)
X = -6
Y = -4
If you move 2 units to the right (x-axis) you go from -6 + 2 which equals -4. And again, you’re not moving up and down so your
y-value stays the same and your new coordinates are (-4, -4)
